Application filed J'u'ne 8,

The object of my'invention is to rovide a, ,vise which is especially adaptedv or being mounted on the table of a machine, for ex' ample a drillii ig press, so as to hold the ar-' ticle on which the Work is to be-done.

My improved vise. is particularly adapted for this work because it is made of two 'independent halves or companion jaws, the gripping faces of which are located a substantial distance abovethe lead screw, thus providing a space between said. companion jaws unobstructed except by the lead-screw, and thereby adapting my vise to receive and clamp elongated articles in a vertical position.

Another feature of my device which renders it especially adapted 'for holding particular articles as above mentioned, are the means provided by me between the clamping faces of the jaw for holding the. work in: difi'erent planes parallel with, and'angularly to the base of the vise. These work-holding means consist in'providing'the jaws of the vise on their clampingfaces-with work sup-- porting ledges, respectively, located adjaholding groove extending parallel with the of the jaws; also in providing one of the clamping faces of the' jaws with. a workholding groove extending parallel with, the top ofsuch clamping face; and further in providin in combination with the jaws movable wor supporting rods supported transversely between the jaws, said rods being movabletodifierent positions so as to support the Work between the jaws in different planes parallel "with and angularly to the base of the vise A further object of my invention is to provide a device of this character which is relatively light and which is simple-in conin% said disc firmly between said jaws;

of Fig. 3, showing the disc'mounted upon I the transverse supporting rods;

Fig. 5 is a section taken on the line 5-5 of Fig. 4, except that an angular article is gripped between the jaws and the supporting rods are arranged accordingly, a portion of onejaw being broken away to disclose said article; 7

Fig. 6 is a plan view of my improved vise gripping a ro or other circular object transversely of said jaws, and shows how the slot between the jaws extends entirely through the vise so that said vise can accommodate articles of considerably greater. length thanthe width of said Haws;

Fig. 7 is a sim ar plan view of my. vise gripping a trapezoidal object between the aws; an 7 Fig. 8 is an elevation of my vise gripping a bar or other-elongated1 ob ect of circular sai aws.

M improved vise especially adapted I for olding objects uponja machine and is here illustrated as being fastened to j the table aflof the drill 5 press b.- My vise is made up of two separable halves c, or companion jaws, each made up of anu'pstanding,'or vertical portionc', the interior opposed'faces of which constitute the clamping faces of the vise, and another portion c integral therewith and extending at right angles thereto, which constitutes 'the base of the jaw. .Said base portions 0 are arranged so as to extend outwardly from the jaw supporting the lead screw. T e base portions 0 are arranged so as not to extend across 7 said space, thus permitting elongated articles tobe gripped transversely between the jaws .or faces. Because of this construction, the capacity of said vise is not limited to articles which are shorter than the width of said jaws. Thus, for'example, if it is de sired to drill in the end of a rod -e, as shown in Fig. 6, s'aidrod is placed on end, and the vise is arranged on the table a so as to extend over the edge thereof, and holding down bolts 11 are passed through the holes 0 in one of said halves. The other half is not fastened but is 'free to slide upon saidtable, butis-also provided with similar-holes c in the other base vise may be fastened table if more conface's, and thus a space d is formed between said jaw faces which extends entirely; through the vise excepting the lead-screw jg. and guide rod is which are rovided for poition, by which my: t0

The inner face of each jaw is provided with a projection g which provides a shoulder or ledge-g.- A series of holes h are drilled through the upstanding portions of said jaws, said series being arranged lengthwise of said jaw portions and are arranged so that a plane tangential to their upper portions would aline itself with the shoulder or ledge g. lVork supporting rods 7;. areslidably supported in any of said series of holes and when in position extend across the slot (1 between the two vise halves. Because of said arrangement, the upper surfaces of said rods are exactly in alinement with theishoulders'or ledges g and thus together form a skeleton-like supporting surface for the article to be gripped between the jaws of said vise. For example, if a circular disc 2' is to be drilled the rods can be arranged, as shown in Figs. 2 to 4, so that they are arranged parallel to each other and support the disc along its opposite edges. The shoulders 9, arranged at right angles to said rods, will support said disc along substantially the remainder of its circular edge. A circular article held in the jaws of the vise has thus four spaced points of support and may be fixedly held for drilling or the like.

A threaded lead-screw j is provided with l a nut 7' journal'ed in one of said halves and said screw is threaded in a nut j held in the other half. Thus, when said screw is turned by its handle 7" it tends to move said unfastened half relatively-towards or-from the other. The rods k being substantially uniform in cross section, thus slide freely in the holes h and thus do not interfere with the clamping action of said jaws upon the object.

I provide a corresponding series of holes through'the jaws, which are arranged along the lower edge of the upstanding portions 0 oneach of the separable halves of said vise. In said holes guide rods k are slidably mounted, similar to the rods h, thus when an angular object Z is being gripped,

its upper end can be. supported by a rod 71. arranged atone side of the lead-screw j,

and its lower end by the guide rod k at the opposite side, as shown in Fig. 5.

When a trapezoidal section m, or other irregular shaped object, is to be gripped between the jaw faces, the supporting rods k can be arranged relatively to the shoulder q to support the same, as shown in Fig. 7. The trapezoidal section m is supported at its wider portion upon the shoulders or ledges g and its narrower portion is supported by a rod 71..

To drill diametrically through a circular rods said rod is held between the jaw faces,

in the manner shown in Fig. 8. LA longi-- tudinal groove n is cut in one of theijaw faces to prevent said circular rod from tend- ,iifg to twist or be displaced by the action of the drill or other tool.

I claim: I

1. A vise comprising relatively movable jaws, each of said jaws formed on the inner face with an article supporting ledge, and article supporting elements. removably cooperating. with both jaws and bridging the space between them, the article engaging surface of such elements being in the supporting plane of the ledges.

2. A vise comprising relatively movable jaws, a series of openings formed in each jaw, a ledge formed on the inner surface of each jaw and tangential to said openings, and a rod cooperating with similar openings of both jaws to thereby arrange the supporting surface of the rod -in the supporting planes of both ledges, whereby an article gripped between the aws and resting 'on the ledges is supported intermediate the ledges by the rod.

3. A vise comprising duplicate jaws, each including an upright jaw face and a lateral bearing member at the lower end of the face, one of the jaws being adapted tobe fixed to a bench or like support and the other of said jaws utilizing its lateral portion as a broad bearing for the jaw on the bench in the movement of the jaw, means cooperatporting an article gripped between the aws at the side edges and intermediate the side edges.

4. A vise comprising relatively movable jaws each formed on the inner face with an article supporting ledge, a, series of openings .formed in each jaw and located relatively to said ledges, and a member removably supported in the openings of both jaws, thereby to provide a supplemental supporting surface in the supporting planes of both ledges, whereby an article gripped between'the jaws and resting on the ledges is supported between the jaws by said member.
